A field experiment was carried out at the Regional Horticultural Research Station, Lebukhali, Patuakhali, during the winter. The experiment was conducted to find out adaptive tomato genotypes suitable for coastal Patuakhali region considering their growth and yield performance. The genotypes of this experiment showed significant influence independently on different parameters of tomato plant. The maximum plant height (86.80 cm) was found in BARI tomato-3. The maximum primary (2.55), secondary (9.55) and tertiary branch (4.48) were obtained from BARI tomato-14. The maximum number of leaves (34.93) obtained from BARI tomato-14. The highest length of largest leaves (35.87 mm) was recorded in BARI tomato-3. The maximum number of flower clusters plant-1 (19.47), number of flowers cluster-1 (6.62), number of fruit cluster-1 (4.84), number of flowers plant-1 (126.3), number of fruits plant-1 (88.0), minimum date for 50% flowering(53.33), highest percentage of fruit setting (76.27), minimum days to first harvest (101.7) were obtained from BARI tomato-14. Moreover, BARI tomato-14 also performed better in respect of yield (3.51 kg/plant and 124.8 t/ha). It may therefore concluded that the genotype BARI tomato-14 showed better growth and yield performance under the coastal condition and suitable for Patuakhali region.Progressive Agriculture 28 (2): 84-91, 2017

“…Excess radiation and high temperatures are the most limiting factors affecting plant growth and finally crop yield in tropical environments [45]. Growth, yield and yield-related components of tomato varieties were affected by water stress while a heat-sensitive variety was more affected than a heat-tolerant variety [46]. GY of barley decreased when sowing was delayed from 10-25 December to 10 January [47].…”

A total of 20 spring wheat genotypes were evaluated under three growing conditions (optimum, late and very late) at the research farm of the Wheat Research Center, Bangladesh to assess the variation in grain yield, protein and starch content under heat stress. All genotypes were significantly affected by high temperature stress in late and very late sowing conditions, resulting in a decrease in days to heading and maturity, ultimately affecting yield, protein and starch content. Considering yield performance, genotype 'E-8' was best under optimum (6245 kg ha -1 ), late (5220 kg ha -1) and very late sowing (4657 kg ha -1 ) conditions while 'E-40' was the worst. With respect to yield reduction, genotype 'E-72' was heat-tolerant (13% yield reduction) while 'Prodip' (49% yield reduction) was heatsusceptible. On the other hand, it was found that the percentage protein increased as heat stress increased. Under heat stress, genotype 'E-65' and 'E-60' had the highest and lowest protein content (15.5% and 12%), respectively. With respect to starch content, 'Prodip' and 'E-37' had the highest while 'E-14' and 'E-72' had the lowest content (64.8% vs. 62.9%), respectively in all sowing conditions.

“…De fato, durante o melhoramento convencional ao aplicar métodos de seleção indireta requer em etapas mais avançadas a utilização de testes diretos. No entanto, apesar de eficiente, a seleção direta requer maior demanda de tempo e recursos (Nahar & Ullah, 2006;Shamim et al, 2014), o que torna relevante a utilização de métodos indiretos nas etapas inicias em um programa de melhoramento.…”

“…Diante disso, aprimorar novas metodologias de seleção no melhoramento genético do tomateiro para tolerância à seca é de fundamental importância. Há relatos de métodos eficientes de seleção direta (Nahar & Ullah, 2006;Shamim et al, 2014;Rocha et al, 2016;Borba et al, 2017) e indireta em tomateiro (Aazami et al, 2010;Morales et al, 2015) visando avaliar a tolerância ao déficit hídrico, no entanto, tais procedimentos demandam maior período de tempo, custos elevados e exigem mais mão de obra para execução.…”
